VALE'ITA V. BROWNQ OF BIG FALLS, MINNESOTA.

To all whom it may concern:

Be it known that I, VALETTA V. BROWN,

a citizen of the United States, residing at' Big Falls, in the count-yof Koochiching and State of Minnesota, have invented certain new anduseful Improvements in Cookers,

and I do hereby declare the following to be a full, clear, and exactdescription of the invent on, such as-will enable others skilled in theart to which it appertains to make and use the same. 7 I

This invention relates to cookers, and it more particularly relates toan improved form of cooker, comprising an oven associated therewith forconveying heated air thereto from an ordinary stove.

An object of the invention is to provide a deviceof this character.which may be used in connection with any cooking stove of ordinaryconstruction.

A further object of the invention is to provide a device of thischaracter which is particularly adapted for use in connection with fluidor hydro-carbon burners.

A still further object of the invention isto provide a cooker of thischaracter'wit-h which the operations of baking, boiling, frying,warming, etc., of foods, may be successfully carried on, at' thesamet-ime, with one and the same burner.

A still further object is to provide a novel arrangementofheatconveyingand control- A still further object form'of-grate, whichis especially adapted to use with this form of cooker;

A still further object; is to provide a great saving of fuel isaccomplished', and in which is combined the maximum of .simplicity,economy and efliciency.

Other objectsand advantages maybe re cited hereinafter andin. theclaims.

In the accompanying drawings which form'a part of thisapplication,-Figure 1 is a vertical sectional view througha fra mentalportion of a hydro-carbon' burrier 0 an improvcdcooker seated over astove-opening above the burner. Fig. 2 is a horizontal fragmcntal andsectional view on the line 2.-2 of Fig. 1, showing the arrangement ofdampers above the oven, and, Fig. 3 is a horizontal sectional view onthe line 33 of Fig. 1, and, Fig. 4 is a plan view of the oven gratefolded on itsdiinges.

Referring to the drawings in which simi- Specification of LettersFatent.

is to provide a novel Patented Apr. 8', 1913. 1912. snai'ivaeeeiso.

lar reference characters designate corresponding parts throughouttheseveral views, a hydro-carbon burner-of ordinary said burner being a"portion of a stove of which the numeral 6 indicates the top and thenumeral 7 indicates the grate, Seated 9 of my improved cooker is'preferably of hollow frusto-conical formation, and the pebase plate 10.This base plate is rovided heated air conduits 12 communicate with theopenings 11, extendingvertically therefrom for approximately lia'lf oftheir length, their medial portion being turned horizontally at 13,thence extending vertically to the top oven plate 14;, the latter beingapertured at .15, forming ports which are in communication withtheheated-air conduits'12.' The top oven plateis also apertured centrallyat16-, so as to form ahot-air port.

The bottom oven plate 17 is seated upon the :tops of the lowersecti'ons'of the heatedair conduits 12, over the horizontal portions ofsaid conduits. The oven bottom 17 is preferably supported by a girder18, the ends. of the girder being supported onposts 19; the latter beingsecured to the base plate of bar-iron, bent into substantially U-shape,or it may be formed from cast-iron or sheet metal, as; preferred.

A damper 25 is rotatably mounted in each conduit 12,

The girder and posts are preferably formedfrom a length -The oven. is preferably cylindrical tlie I beingprovided, of any proper form,and"ar- The wallQO is 1provided withsupporting, latter beingforlncd in two semi-circular '100 side walls 20are provided with apertures therefrom is partially absorbed by the foodlll) being provided with an aperture 25, adapted to be turned lnto andout of registry with the aperture 25, by means of a knob orb a.) lhisform of camper, being 01 ordi- 5 naryconstruction, is not described infur ther detail. The openings between the bars oit grate 23 arerelatively small or narrow, their combined capacity being approximatelyequal to that of the conduits, so that all oi? the heated-air cannotpass directly upward from the apertures 25; but a consid- .erableportion of the air is directed toward the central portion of the oven,as indicated by the arrows under the grate Therefore, the heat isthoroughly distributed in all parts of the oven. After passing throughthe oven, the heated-air continues upward through the port 16, into thewarmair chamber 20, and is caused to spread laterally by means of theWarming plate or crown 27. The crown 27 is' provided with outletapertures 28, any desired number oi" which may be employed, but wh chare preterably equally spacedfaroiind the oiit'er'edge" portion of thecrown. The upper side wall 20 is apertured at 28, and the arm 29 of adamper member 30 extends through the aperture 28, being slidably seatedtherein; a handle 31 being provided for sliding the an arm 29 and movingthe damper 30 over the central port 16. The damper 30 is provided withlaterally and rearwardly curved arms 32, which are pivoted at to thedamper levers 34:; the latter being united with 35' dampers 35, foropening and LlOSlIlglilQ thereto through the medium of the plate 10 and,the bottom of the cooking utensil. When it is desired to bake or roastan article of food, within the oven, the same is placedupon the plate 17or upon the grate 23, and the handle 81 is manipulated so as to regulatethe damper members, by which the central'port 16 maybe closed,lwhil.esimultaneously opening the ports 15 or vice versa. When the port 16 isopened the ll'lr' tensitv oi the heat within the oven is in 1 thetollowin claims.

'L']"tl5(3(l, while if the ports 15 are opened and the port 16 closed,the heated-air will pass around the oven, only importing a smallquantity of heat thereto. However, the ports 15 and 16 may be partlyclosed and partly opened, when it is desired to bake or roast an articleof food 5 xwly; and it is obvious that the heat within the oven may beregulated perfectly, by proper manipulation of the dampers. I may alsoutilize the conoavoconvexecl base flange for heating sad-irons, byseating their under sin-tacos against the inclined outer surface oi thebase flange.

it is obvious that I have provided a de vice of this character which isfully capable of attaining the foregoing objects, and in a thoroughlypractical and etticient manner.

1 do not limit my invention to the exact I details of construction,combination and arrangement of parts, herewith described 'audillustrated, but my invention may only be limited by a reasonableinterpretation of What I claim is: 1. In a cooker, an oven havmga doorand having grate-supporting lugs onits Wall,

and grate con'iprising a pair of similar grate members hinged togetherand supported by the hinge at the middle of the grate and adapted tonormally rest upon the lugs and to be folded together forremovaltiirough the door, substantially as shown and specifled.

In cooker, an oven having an apertured conduits for conveying heated airinto the oven, a chamber above the oven and separated therefrom by thetop of the oven,

said conduits being provided With ports for establishing communicationbetween the .conduits and the chamber, and a damper mechanism pivotallyconnected to the oven 3 top Within the chamber and including meansextending outside of the chamber for simultaneously opening the apertureof the oven 1 top and closing the ports through which the chamber andconduits communicate.

ln testimony'vvhereof I have signed my name to th s spec1tica't1on inthe presence of two subscribing Witnesses.
